Re: Special Utah Counsel Opinion regarding Utah corporations Bluehost Inc. and FastDomain Inc. Registration Statements on Form S-3

Ladies and Gentlemen:

We have acted as special Utah counsel to Endurance International Group Holdings, Inc., a Delaware corporation (“Holdings”), Bluehost Inc., a Utah corporation, and FastDomain Inc., a Utah corporation (each a “Utah Company” and collectively, the “Utah Companies”), in connection with the Registration Statements on Form S-3 (the “Registration Statements”) filed with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”) in connection with market-making activities by an affiliate of EIG Investors Corp., a Delaware corporation (the “Company,” a wholly owned subsidiary of Holdings), in respect of up to $350,000,000 aggregate principal amount of the Company’s 10.875% Senior Notes due 2024 (the “Notes”). The Notes are fully and unconditionally guaranteed by the Utah Companies, and several additional guarantors identified in that certain indenture dated as of February 9, 2016 pursuant to which the Notes were issued (the “Indenture”) among Holdings, the Company, the Utah Companies, the other parties named therein, and Wilmington Trust, National Association, as trustee (the “Trustee”), as supplemented by the First Supplemental Indenture thereto dated as of February 9, 2016, and as further supplemented by the Second Supplemental Indenture thereto dated as of April 25, 2019 between P.D.R. Solutions (U.S.) LLC, a Delaware limited liability company, the Company, and Trustee. The Indenture includes the guarantees of the Notes by the Utah Companies and the other guarantors party thereto (the “Guarantees”).

For purposes of giving the opinions hereinafter set forth, we have examined originals or copies, certified or otherwise identified to our satisfaction, of the following:

(i) the Indenture and the Guarantees set forth therein;

(ii) the articles of incorporation of each of the Utah Companies and all amendments thereto (the “Articles”);

(iii) the bylaws of each of the Utah Companies and all amendments thereto (the “Bylaws,” and together with the Articles, the “Governing Documents”); and

(iv) such records, agreements, instruments and other documents as we have deemed relevant and necessary as a basis for the opinions hereinafter set forth.

For the purposes hereof, we have assumed, with your permission and without independent verification of any kind that: (a) the signatures of persons (other than, solely with respect to the Indenture, the authorized representatives of the Utah Companies) signing all documents in connection with which this opinion is rendered are genuine and authorized; (b) all natural persons executing agreements, documents or instruments examined or relied on by us have the requisite legal capacity to do so; (c) all documents submitted to us as originals or duplicate originals are authentic; (d) all documents submitted to us as copies, whether certified or not, conform to authentic original documents; (e) all parties to the Indenture (other than the Utah Companies) will act in accordance with, and will refrain from taking any action that is forbidden by, the Indenture; and (f) the parties to the Indenture (other than the Utah Companies) and any agent acting for any of them in connection with the transactions contemplated by the Indenture, have acted in good faith and without notice of any defense against the enforcement of any rights created by the Indenture.

As to questions of fact relevant to this opinion, we have relied upon certificates and oral or written statements and other information of representatives of the Utah Companies, public officials or others.

We are opining herein as to the effect on the subject transaction only of the internal laws of the State of Utah with respect to our opinions set forth in this letter. Except as described in the previous sentence, we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or as to any matters of municipal law or the laws of any other local agencies within any state. In addition, our opinions are based upon our consideration of only those statutes, rules and regulations which, in our experience, are normally applicable to transactions of the type contemplated by the Indenture.

Furthermore, in rendering the opinions expressed below, we have assumed, with your permission and without any independent investigation or verification of any kind, that: (a) all parties to the Indenture (other than the Utah Companies) are duly organized, validly existing and in good standing under the laws of the jurisdiction in which they were organized and of each other jurisdiction in which the conduct of their business or the ownership of their property makes such qualification necessary, with the requisite power and authority to execute and deliver the Transaction Documents and to perform their obligations thereunder; (b) the Indenture has been duly executed and delivered by the parties thereto (other than the Utah Companies); and (c) the Indenture constitutes the valid and legally binding obligation of the parties thereto (other than the Utah Companies).
